Abstract
Fibromyalgia (FM) is often accompanied by chronic fatigue syndrome (CFS). It is a poorly understood disorder that mainly affects women and leads to chronic pain, fatigue, and insomnia, among other symptoms, which decrease quality of life. Due to the inefficiency of current pharmacological treatments, increasing interest is being directed towards non-pharmacological multicomponent therapies. However, nutrition and chronobiology are often overlooked when developing multicomponent therapies. This narrative and critical review explore the relevance of nutritional and chronobiological strategies in the therapeutic management of FM and the often-associated CFS. Reviewed literature offers scientific evidence for the association of dietary habits, nutrient levels, body composition, gut microbiota imbalance, chronobiological alterations, and their interrelation with the development and severity of symptoms. This review highlights the key role of nutrition and chronobiology as relevant and indispensable components in a multidisciplinary approach to FM and CFS.

Abstract
The efficacy of current pharmaceutical treatments for fibromyalgia are limited. Vitamin D has shown promise in relieving pain. However, there is a lack of comprehensive analysis of psychological outcomes with vitamin D supplementation in fibromyalgia. This study aimed to investigate the impact of vitamin D supplementation on psychological outcomes and quality of life in fibromyalgia patients, given the unmet clinical need for effective treatment options. A meta-analysis of randomized controlled trials comparing vitamin D to placebo and prospective studies examining changes before and after vitamin D supplementation for patients with fibromyalgia was conducted to evaluate the effects of vitamin D on psychological outcomes, quality of life, and pain scores in patients with fibromyalgia. Databases were searched for relevant articles published from earliest available date to October 31, 2022. (PROSPERO number, CRD42022369889). We included 8 trials with a total of 694 participants and found that vitamin D supplementation had significant positive effects on physical function (standard mean differences (SMD) = 0.44, 95% CI = [0.10, 0.77 ]), role limitations due to emotional health (SMD = 0.57, 95% CI = [0.32, 0.82]), social function (SMD = 0.50, 95% CI = [0.08, 0.93]), and general health (SMD = 0.36, 95% CI = [0.11, 0.61]). Improvement of the Fibromyalgia Impact Questionnaire (FIQ) scores was noted (SMD = -0.414, 95% CI = [-0.808, -0.021]), but not on the Visual Analog Scale (VAS) (SMD = -0.15, 95% CI = [-0.771, 0.471]) and the Beck's Depression Inventory (BDI) scores (SMD = -0.456, 95% CI = [-1.27, 0.30]). In conclusion, vitamin D supplementation might be an alternative option for improvement of psychological outcomes and quality of life in patients with fibromyalgia.

Abstract
Aim: Vitamin D deficiency is a prevalent condition among the general population, all around the world. Vitamin D deficiency is defined as serum levels of 25-hydroxy vitamin D lower than 20 ng/ml (50 nmol/ml). It is a known actor in the skeletal system through the regulation of calcium and phosphate metabolism and bone mineralization. Still, the role of vitamin D as an immunomodulator is yet to be acknowledged by healthcare practitioners as a cause, precipitating factor, and contributor to a variety of diseases. Vitamin D is shown to be an actor in multiple sclerosis, rheumatoid arthritis, insulin-dependent diabetes mellitus, and irritable bowel syndrome. Fibromyalgia syndrome (FMS) is a chronic disorder associated with a severe pain that can affect a patient's musculoskeletal system, daily routine, and mood. The clinical presentation encapsulates other disorders such as lethargy and sleep problems, brain fog and other cognitive issues, and physical and psychiatric symptoms. Methods: We have used PubMed and ResearchGate in the reviewing process of our paper. We tried to address as many topics as we judged to be adequate and relevant for the practicing clinicians. Results: Management of fibromyalgia syndrome is both nonpharmacologic and pharmacologic, which are provided in a stepwise fashion. Yet, the management of FMS remains a challenge, heeding a multidisciplinary approach. Among the dietary interventions, we chose vitamin D and its effects on FMS. Literature shows that supplementation improves pain caused by fibromyalgia syndrome, yet specific recommendations are still to be created. Conclusions: We call on all the relevant governmental bodies, public health experts and health policy makers, healthcare practitioners, and the civil society to use novel data related to fibromyalgia syndrome, and in a broader perspective, the integral role of vitamin D.

Abstract
BACKGROUND Gestational diabetes is one of the most common metabolic disorders during pregnancy. Some studies have reported the effect of vitamin D deficiency on the incidence of this disorder. Therefore, the purpose of the present study was to determine the effect of vitamin D supplementation on fasting blood glucose (FBG) levels, fasting blood insulin (FBI) levels and insulin resistance index (HOMA-IR) (primary outcomes) and symptoms of depression, musculoskeletal pain, frequency of gestational diabetes and the frequency of abortion (secondary outcomes). METHODS In this triple-blind randomized controlled trial, 88 pregnant women at 8-10 weeks of pregnancy who had the vitamin D of less than 30 ng/ml were randomly assigned to the vitamin D group (n = 44) and control group (n = 44) using block randomization. The vitamin D group received 4,000 units of vitamin D tablets daily and the control group received placebo tablets for 18 weeks. Independent t-test, Mann-Whitney U and ANCOVA tests were used to analyze the data. RESULTS After the intervention, there was no statistically significant difference between the two groups in terms of FBG (P = 0.850), FBI (P = 0.353), HOMA-IR (P = 0.632), mean score of depressive symptoms (P = 0.505), frequency of gestational diabetes (P = 0.187) and frequency of abortion (P = 1.000) and there was only a difference in terms of serum vitamin D level (P = 0.016) and musculoskeletal pain including knee pain (P = 0.025), ankle pain (P < 0.001) and leg pain (P < 0.001). CONCLUSION Vitamin D could improve the musculoskeletal pain in pregnant women but couldn't decrease FBG, FBI, HOMA-IR, depression symptoms score, incidence of GDM and abortion.

Abstract
Fibromyalgia syndrome (FMS) and chronic widespread musculoskeletal pain (CMP) are diffuse suffering syndromes that interfere with normal activities. Controversy exists over the role of vitamin D in the treatment of these diseases. We carried out a systematic literature review of randomized controlled trials (RCT) to establish whether vitamin D (25OHD) deficiency is more prevalent in CMP patients and to assess the effects of vitamin D supplementation in pain management in these individuals. We searched PubMed, Physiotherapy Evidence Database (PEDro), and the Cochrane Central Register of Controlled Trials (CENTRAL) for RCTs published in English from 1 January 1990 to 10 July 2022. A total of 434 studies were accessed, of which 14 satisfied the eligibility criteria. In our review three studies, of which two had the best-quality evidence, a correlation between diffuse muscle pain and 25OHD deficiency was confirmed. Six studies, of which four had the best-quality evidence, demonstrated that appropriate supplementation may have beneficial effects in patients with established blood 25OHD deficiency. Eight studies, of which six had the best-quality evidence, demonstrated that 25OHD supplementation results in pain reduction. Our results suggest a possible role of vitamin D supplementation in alleviating the pain associated with FMS and CMP, especially in vitamin D-deficient individuals.

Abstract
Several studies have indicated a correlation between vitamin D deficiency and widespread chronic pain syndromes, such as fibromyalgia. During this study, the effect of supplementation with vitamin D in association with physical exercise in patients with fibromyalgia was evaluated, in terms of improvement of pain, functional capacity and quality of life, also evaluating the presence of any differences in age. A single-center, observational, comparative study was conducted in 80 fibromyalgia patients. They are randomized into 2 groups: Group A, consisting of patients ≤50 years; and group B, consisting of patients >50 years. Both received weekly supplementation with 50,000 IU cholecalciferol for 3 months in association with a rehabilitation protocol. Patients were assessed at enrollment (T0), 3 months (T1), and 6 months (T2) from the initial assessment with blood vitamin D dosage and administration of rating scales (NRS, FIQ, and SF-12). From the comparison between the two groups, we have seen that in young people, supplementation with high-dose vitamin D improves short-term musculoskeletal pain and long-term functional capacity. Conversely, musculoskeletal pain and long-term quality of life improve in the elderly. Supplementing with high doses of vitamin D in fibromyalgia patients improves the quality of life and pain in the elderly and also the functional capacity in the young.

Abstract
BACKGROUND Recent studies have found potential benefits of vitamin D in relieving pain, while the results from randomized controlled trials of vitamin D for fibromyalgia have been promising. We conducted a systematic review and meta-analysis to evaluate the efficacy of vitamin D in the treatment of fibromyalgia. RESEARCH DESIGN AND METHODS PubMed, Web of Science, Embase, and Cochrane Library databases were systematically searched. The language used was limited to English. We selected only randomized controlled studies that reported vitamin D versus placebo-controlled cure for fibromyalgia. After extracting valid data, a meta-analysis was performed using Stata version 12.0. The major outcome in the pooled analysis was the Fibromyalgia Impact Questionnaire and Visual Analogue Scale (VAS) changes in fibromyalgia patients before and after treatment. The pooled effects were analyzed as mean differences and 95% confidence intervals. RESULTS : Five studies including 315 participants were identified. These studies found that vitamin D was effective in reducing Fibromyalgia Impact Questionnaire scores compared with that in the control group, with significant differences (weighted mean difference = -7.82, 95% confidence interval: -12.05 to -3.59, P < 0.001). However, there was no statistical difference in VAS between the two groups (weighted mean difference = -0.60, 95% confidence interval: -1.38 to 0.17, P > 0.05). CONCLUSIONS Data from randomized controlled studies suggest that vitamin D supplementation may be an effective fibromyalgia therapeutic approach.
